Reflected XSS via unescaped exception argument keys
Published May 4, 2024 · Updated Aug 16, 2024
Reflected XSS in ThinkPHP 8.0.3 allows remote attackers to run script in a victim's browser through a crafted GET request. The parse_args logic in think_exception.tpl inserts attacker-controlled argument keys into the debug page without HTML encoding. Exploitation requires a route that binds attacker input as a function argument, debug error output, and victim interaction; script execution can read session cookies and file details shown on the page.
